The possibly contaminated raw pork products were shipped to retail stores in New Jersey, New York, Pennsylvania and nine other states, according to the U.S. Department of Agriculture Food Safety and Inspection Service.

Officials said they found the plastic after customer complaints. No one has reported becoming sick from the contamination, according to the FSIS.

"Consumers who have purchased these products are urged not to consume them," the agency said. "These products should be thrown away or returned to the place of purchase."
